Why would people benefit from learning sign-language?

It allows you to communicate with hearing-impaired; you and friends can have secret conversations without others understanding, or disguise the conversation with another more mundane one; it is also a sign of compassion, intelligence and respect - all of which are good character traits, and knowing an additional language is also a decent jobskill - that you have firstly learned a language and can then use it to assist others who may not otherwise be able to communicate.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
